Turning Off DHCP Server on Netgear Wireless Cable Gateway CGD24N
October 9, 2016
Posted by on
The Netgear Wireless Cable Gateway model CGD24N supplied by Bigpond in Australia can spend a second life as a simple Ethernet switch. However it assigns DHCP addresses out of the box which can really upset a home network if you’re not expecting it.
Your wireless router might be assigning addresses from one range but you keep finding guest devices assigned something from the 192.168.100.0/24 range.
It’s not that straightforward to find the DHCP on/off switch. The steps to find it are thus:
1. Log in to gateway admin interface, select NAT from menu
Select NAT from menu on left-hand side
2. Turn NAT on, click apply
Select NAT on checkbox, click apply
3. Select LAN IP from left hand menu
Select LAN IP from left hand menu
4. Select DHCP no radio button, click apply
Select DHCP no radio button, click apply
